Replacing gym membership with elliptical

Hi,

If you were paying $25/month/person for 2 people to have a gym membership, and all they did was use the elliptical, would it make sense to buy an elliptical machine and cancel the gym memberships?Depending on the model we purchase, it would be 8-16 months before we break even but the appeal to me is being able to use it whenever I want. Right now I can really only go to the gym during my lunch break and between travel + shower, I have 20 minutes on the machine and no time to eat.I also know that home fitness equipment is one of those purchases that most people regret?
